Your entire residence should be a refuge that’s warm and comfy in the cold months and cool and comfortable in the summer. However, residents in some multi-level residences find the upper floor is stubbornly hotter or colder than the main floor.
This could simply be because most thermostats in a house are on the main floor, which is where people spend the greatest amount of time—in the living room, kitchen, etc.—so it makes sense to set the temperature according to how it feels on the first floor.
However, temperature discrepancies between the upstairs and downstairs could also be because of trouble with your HVAC system. Some of these challenges can be resolved relatively quickly while others might require more extensive and costly fixes. Here, the professionals at Olde Towne Heating & Air will help you determine why the upstairs of your home is hotter than downstairs, or vice versa.
Why Is My Upstairs So Hot?
The phenomenon of the upstairs of a two-story home feeling hotter than the downstairs can be attributed to several factors. Number one, heat rises, so it’s natural for the second floor of a home to get hotter than the main floor. Poor insulation in the attic or roof can exacerbate this issue by permitting heat transfer from the roof into the upstairs rooms.
Another common reason is that the air conditioning is not powerful enough to cool the entire home, causing it to struggle to cool the upstairs sufficiently.
To tackle these issues, homeowners could add extra insulation in the attic and make sure their home has proper ventilation. If there’s a question of whether the AC is the ideal size for the home, call an experienced HVAC company like Olde Towne Heating & Air inspect the unit. A knowledgeable professional also can help find a unit that's better suited for your home if you need air conditioning installation or replacement.
Why Is My Upstairs So Cold/Not Heating?
When the downstairs of your home is warm, but it’s extremely chilly upstairs, that can cause an ice-cold night for anyone whose bedrooms are on the upper floor. The most prevalent reasons an upstairs not heating like it should are the insulation levels and the ductwork.
Inadequate insulation allows cold air to leak through the home’s attic or walls and contribute to heat loss, creating colder temperatures on the upper levels. It’s important to make sure your home has a thick, level layer of insulation in the attic and appropriate insulation in the walls to keep the cold out and the heat inside.
The ductwork in a home plays a critical role in disseminating conditioned air throughout different locations of the building. However, issues with the ductwork can contribute to the upstairs being colder than the main level. A frequently reported cause for this is improper airflow balance. The ducts may not be the right size or design, which results in an uneven distribution of air between the floors. This can cause more warm air to be directed to the downstairs, causing insufficient airflow—which is the heated air—on the upper story.
Another factor with ductwork is the location of the supply and return vents. If there are fewer vents on the upper level or they are not correctly located, it can restrict air circulation and cause substandard heating or cooling. Additionally, leaks or gaps in the ductwork can allow air loss, lowering the overall efficiency of the HVAC system and making the temperature difference more pronounced.
To figure out why the upstairs is colder than the downstairs, homeowners should hve their ductwork checked by experienced experts like the team at Olde Towne Heating & Air to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in additional vents or adjusting existing ones can help enhance airflow and ensure a better temperature balance between the upstairs and downstairs.
How You Can Fix a Hot or Cold Upstairs?
If your upstairs is hotter or colder than the rest of your house, an HVAC zoning system could be a highly effective solution.
An HVAC zoning system separates the home into distinctive zones, which each have their own thermostat and damper system so the homeowner can control the heating or cooling of each zone.
This system can be especially useful in situations where the upstairs of a multi-story home is too hot or really cold while the main floor is comfortable. By investing in a zoning system, homeowners can control the temperature independently in each zone, enabling them to address specific hot or cold spots effectively.

Why Is My Upstairs So Humid?
In addition to the upper story being hotter or colder than the rest of the house, another issue in multi-floor homes is when the higher levels are more humid than the lower level.
A frequent reason for excess upper floor humidity is weak ventilation on the upper floor, which can cause increased humidity levels. As is often the case with temperature differences between floors, poor insulation or sealing in the attic or walls may let warm, humid air from outside infiltrate the upstairs rooms. And, if there are any leaks or plumbing issues on the upper floor, that can also create excessive moisture in that area of a home.
To manage humidity problems, homeowners can increase ventilation by getting fans or opening windows to promote airflow. Adding more insulation in the attic and better sealing the attic and walls can help protect against external moisture from entering the upstairs. Locating and repairing any leaks or plumbing issues is also critical.
Depending on the levels of moisture found in the home, a whole-home dehumidifier could be another worthwhile tool to reduce humidity on the upper and lower floors.
